CHARLES (MBBS, OF NEW YORK, Y.

TYPE-WRITER.

.s Be iti'kiiowii that I, CHARLES Grises, a citizeii of the Unitedv States, arid a resident of the the couittjv 4and State or" New York, have invented a iiew arid improved Typewriter, of which the following isa full, clear7 aiid exact description. p

This iiiveiitioii relates to typewriters, and especialliv to that type of these machines which oiiiplojvs type hars.

The. oliject oi the invention is to produce au improved airazigeiiieiitiwhich Will facilitatethe renewal of the type liars when they hecoiiie wori'i.

'.lliel invention consists iii the construction describe-d -hereinafter andA particularly -set forth iti the claims.

Reference is to he had the accompanyiiig drawings ioriiiiiig a part of this specificatioii, iii which similar characters of refe-rence. indicate corresponding parts iii all the jfigures. Figure 1 is a vertical section showing some of' the. parts of a typewriter and illustrating the iii fe'iitioii; Fig. Z shows the upper portio'ii ofthe mechanism .of Fig. 1, iii elevatiori; this view 'iiisy'he considered as a section oii the lis-,e lf2 oi'liig. 1,' and Fig. 3 is a side elevation showin@ a portion of a type bar whe-ii coiistructei according to the present iiiveiftioii. l

lteferriii-.g more particularlyT to the parts,

typewriter, there heilig a similar plate at the opposite erid oi the case. The-se end plates are co'iulected rie'ar the rear of the iiischiiie oy a lever bridge 2, -which consists simply oi a horizontal transverse liar as showi'i. similar transverse 1oar 3 is provided conrectiiig the eiid plates i hear the middle of the.

li'L the upper portion of' the mechanism lie tweeii the eiiil platos 1, i provide a segiiieit consisting ot a plate of substantially semicircular ioriii, :is irdicated iii Fig( 2. At its lower ed e this piate or segment is provided l with a p urality of siots or sockets 5 which are disposed radially from the center of the are upoii which the lower edgel of the segL ynient is disposed.' At their upper extremities these slots are oriiiod with enlargements or round grooves 6 which extend inwardly i'rom the forward vertical face 7 of the segu Specification vof Letters Patent.- Application led Miti-ch 8,1-7. Serial No. 361,233.

` are of substaiitialliv the Each of the type oars 8 is suhsta'iitially of Patented May 21, 1907'.

the form shown, presenting an elongated hodv, near the free eiid of which the type bar 9 is attached. At the point 10 each typo bar is pivotally attached to a shoe or hanger l1, This part consists simpljvr of a thin plate presenting, at its upper edge, au enlarged head or tongue 12. The liar is pivote-il to the plate near the lower edge thereof, as shown iiiFig. 3. The type lier is provided with a rearwardly7 extending toc 13, presenting a-slot 14 for a purpose more fully hereinafter. These hangers 11 are removalilj,Y mounted in the slots 5 iii the manner indicated. The bodies oi the plates width of' the slots so that they fit neatly therein.` The tongues 12 are received iri theI enlargementsor grooves so as to interlock the hangers iii the slot' aud. prevent the hangers i'roiii being displaced downwardly iii the slots. As shown iii Fig. 1, the slots 5 are out completely through the rear face oi the segment; oii its rear face the segment-4 is l'oriiied with a groove 1.5 which is curved to coiiioriii to the shape ol the segment; this groove is undercut oii lio th sides, as shown so that it will retain i1. curved seathar 16 which is thrust iii through the operi end oi' the groove. This har closes the hot toms of the slots and forii'is a seat tor'the hangers to come. against when they are shoved into the slots or sockets. lhe iriiier vertical edges oi the l'isiigers are provided with notches 11- iespectivelv iii which the seat-har 16 lies. The upper portions ol' the. hangers 11 are cut away, as indicated at the edges 1T so that these. edges l? are iii suhstaiitial aliiieiiieiit with the l'oiwiiid lace 7 ofV the segment. The hodies of the hangers proiect beyond this point so is to eiiahlo theiii to he seized when they." site to he removed. They are held in. the. slots liv inea-iis of a lock har 18, which lock har is oi curved form, .as indicated iii Fig. 13; it held against the edges 1'? of the hangers li); moaos ol small clips or clamps 11i? which are fastened to the outer iaceof the segiiieiit hir suitable screws 2l). These which will appear ol the har.

Moveiiieiit is give-ii 'ro each typo har hy means oi a hey-lever 22, iiliichis lornied at vits rear extremity with a hook 122-3 engaging the under side oi the lfii'idgc LZ. Near the bridge 2 a spring 2l 4is provided, which thrusts, against the under sido of the lever ici' claii'ips are cut :is iiidi` .ce-ted iii Fig. 1 so as to present sockets .21 oii l their lower faces which engage the youter side by that key.

Aio

and maintains the 'saine in an elevated position. The forward end of the lever projects from the typewriter case in the usual manner, and. is provided with a button 25 which indicates the character of the type operated On the bridge 3 a rocker 26 is provided, which is formed at one side with a slot 27, and this slot is engaged by a pin 28 carried by the lever 22 as shown. This rocker 213 extends upwardly, and is provided at its upper extremity with a pin. 29 which is lreceived in-theaforesaid slot 14. From the arrangement described, and illustrated in Fig. 1, it should be understood that when the lever 22 is depressed, the upper portion of the rocker 26 will move toward the right in such a way as to elevate the free end of the t Ype bar 8. In. this way any one o1 the type' ars may .be-operated se as to bring the type to the printing pression of the type is taken.

Whenever it is necessary to remove one of the type bars to repair or renew the part, this is readily accomplished by loosening the clamps 19 in. such a wayas to enable the lock bar 1S to be shifted longitudinally' in the clamps. The lock har is, of course, shifted far enough to uncover the hanger of the type bar which is to be removed, whereupon the hanger is simply slid forwardly out of its slot, and the toe 13 of the type bar is then disengaged from the pin 29. The new type bar is then attached to the pin 29, as will he readily understood, and its hanger is then forced. rearwardly into the slot so as to occupy the position occupied by the hanger ot the original type bar. `The lock bar 18 is then slid back into its normal position/and secured by tightening the clamps 19 in the manner suggested.

lAttention is called to the sim licity of the operation of renewing the type gar when the parts are constructed according to this invention. It is unnecessary to remove any of the contiguous parts except the lock bar 18,

and this har even is not removed, but simply displaced slightly from its normal position.

point 30 where the'im-fl Having thus described my invention, I claim as new and desire to secure by Letters Patent;

1. In a machine of the class described, in combinatioma segment having sockets in vthe edge thereof, a plurality of l'iangers sliding respectively into said sockets interlocking -therewith and projecting beyond the edge of said segment, and type bars pivotv ally attached to the projecting parts oll said. hangers beyond said edge. Y

2. In a machine "ot the"class described, in combination, a vertically disposed segment having radially disposed slos in the edge zontally into said slots, an interocking ronnection between said hangers and said. slots preventing a radial movement thereof in said slots, said hangers pro'eoting beyond the edge of said segment, an type bars pivotaly kattached to said hangers on the projecting parts thereof.

3. In a machine of the class described, in combination, a iixed member having a plurality of slots, said slots having grooves therein, a plurality oi' hangers receivedin said slots and having tongues adapted.' to slide into said grooves, and a plurality of type hars respectively pivoted on said hangers.-

4. In a machine ofthe class described, in combination, a segment having a pfuraity of slots with grooves'therein, a pluradl'y of hangers received respectively iii-said slots and having tongues received in said grooves., a curved lock bar rernovahfgr attached 'to said segment adjacent to said hangers and locking the same against wiihdrawal, and. a plurality of type bars-pivotay mounted rcspectively on said hangers.

In testimony whereofI have signed nig name to this speeiiication in the presence of two subscribing witnesses.
